Building Products Plain EPS Insulation

EIFS

Cellofoam EIFS Insulation Board is a lightweight, closed cell, rigid foam insulation specifically manufactured from expanded polystyrene (EPS) to EIFS system requirements. Cellofoam EIFS Insulation Board meets or exceeds ASTM E2430, Standard Specification for Expanded Polystyrene Thermal Insulation Boards for Use in Exterior Insulation and Finish Systems as well as the requirements of Type I EPS in ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.

Cellofoam supplies insulation to the top EIFS systems in the United States, such as DryVit, STO, Parex, and BASF, and in several cases manufactures to specific, proprietary, EIFS system specifications. While most Cellofoam EIFS Insulation Board is manufactured in flat boards for OEM systems, we also produce a wide variety of EIFS architectural shapes which may be viewed in our shapes catalogue. Cellofoam additionally fabricates custom shaped designs using computer driven hot wire cutting tools.

Our EIFS Insulation Board is made from premium EPS with excellent dimensional stability, compressive strength, and water resistance. Cellofoam EIFS Insulation Board is aged per ASTM E2430 specifications for added dimensional stability and very low moisture content. Both durable and flexible, Cellofoam EIFS can withstand large temperature change as well as reasonable structure movement without damage to the strong outer surface finish. Pre-cut drainage channels are optional.

Advantages

Maximum Bonding

Because maximum bonding ability is critical, Cellofoam EIFS is manufactured with a smooth, textured surface compatible with many types of adhesives and exterior finish coats to ensure a long-lasting and structurally sound wall system.

Code Approvals

Underwriters Laboratory listed, UL ER7260, for exterior insulation and finishing systems (EIFS). Please consult local building codes for system requirements.

Stable R-value

The R-value of EPS is permanent because the only gas in EPS is air. Unlike Polyiso or XPS whose blowing agents outgas and therefore lose R-value, EPS R-values do not degrade over decades of use.

Moisture Resistant

Cellofoam EIFS breathes, is quick drying, and does not readily absorb moisture from the air. The passage of moisture as water vapor through EPS reduces the risk of moisture damage to the wall or the peeling of exterior material.

Premium Quality

Meets or exceeds ASTM E2430 and C578 specs, with excellent dimensional stability & compressive strength.

Environmentally Friendly

Cellofoam EIFS EPS contains no formaldehyde or ozone-depleting CFCs or HCFCs. It is 100% recyclable and may contain recycled material.

Manufactured to Your Needs

Cellofoam EIFS Insulation Board is manufactured in 24 x 48 inch boards with thicknesses from 1 to 6 inches. Pre-cut drainage channels are optional. Most EIFS systems require Type I (1.0 lb/ft3) EPS although ASTM C578 nominal densities up to 2.0 lb/ft3 are available with EIFS System approvals.
